But he says he wouldn’t have been able to carry out the project without speaking to Zappa’s widow Gail, who died in October of last year.

The Lost Boys and Bill And Ted’s Excellent Adventure actor Winter tells Billboard: “Gail Zappa – Frank’s wife and the formidable front end of the Zappa Family Trust – was especially supportive. She told me that she had refused a lot of people who approached her about his story in the past, asking for access to the family and Frank’s personal archive and unreleased material.

“But even though Gail gave me her blessing, she also knew her time was limited. Tragically, Gail had already been diagnosed with terminal cancer. So, once she decided to let me make this film, I started filming interviews with her right away.

“I’m glad to say that we got some amazing footage before she passed away in October of 2015, because there’s no way we could tell Frank’s whole story without her.”

The Kickstarter campaign has already exceeded its $500,000 goal and currently sits at $568,000.
